INTRODUCTION

The U.S. Geological Survey periodically assesses petroleum resources of areas within the 

United States and the world. The purpose of this report is to explain the development of 

an analytic probabilistic method and spreadsheet software system called Analytic 

Spreadsheet Energy Software System (ASSESS). The ASSESS method is based upon 

mathematical equations derived from probability theory. The ASSESS spreadsheet can be 

used to calculate estimates of the undiscovered conventional oil, gas, and NGL resources 

in an assessment unit or play. An assessment unit is a mappable volume of rock in a total 

petroleum system. First, the geologic assessment model is defined; second, the analytic 

probabilistic method is derived; and third, the spreadsheet ASSESS is described.

GEOLOGIC ASSESSMENT MODEL

The geologic assessment model is called the Seventh Approximation and is described in 

Schmoker and Klett (1999). The geologic assessment model for an assessment unit 

consists of the following components (see figure 1 for additional descriptions):

A. A set of four assessment-unit probabilities:

1. Charge

2. Rocks

3. Timing

4. Access

B. A set of six random variables for oil fields and a similar set for gas fields (12 total):

1. Number of undiscovered fields

2. Sizes of undiscovered fields

3. Ratio of coproduct A

4. Ratio of coproduct B

5. Percent allocation to parcel (or land entity)

6. Percent allocation to offshore

C. A set of three descriptive parameters for each of the 12 given random variables:

1. Minimum (F100)

2. Median (F50)

3. Maximum (FO)

An example of the basic input data form for the Seventh Approximation is given in figure 

1. The assessment unit, called Frio Rio Grande Embayment Gas, was assessed by 

Christopher J. Schenk as part of an assessment of the Padre Island National Seashore 

(Schenk and others, 1999).

ANALYTIC PROBABILISTIC METHOD

The geologic assessment model Seventh Approximation is a description of a complex 

probability problem that needs to be solved for the estimates of the undiscovered 

petroleum resources. The method derived herein, called ASSESS, is a system that solves 

the problem. That is, the model Seventh Approximation is the problem, and the method 

ASSESS is a solution. Simply stated, ASSESS is a solution of Seventh Approximation.

The 12 given random variables are assigned probability distributions as probability 

models that are based on the descriptive parameters (F100, F50, and FO). That is, each 

given random variable is assigned a probability distribution with the specified descriptive 

parameters: minimum, median, and maximum. It is important to realize that the ASSESS 

method does not depend upon the assignment of probability distributions in that any 

assignment can be accommodated. The assignment is an operational decision. The 

following probability distributions were assigned to the set of six given random variables 

for oil fields and also for gas fields:

1. Number of undiscovered fields: Median-based triangular distribution

2. Sizes of undiscovered fields: Truncated shifted lognormal distribution

3. Ratio of coproduct A: Median-based triangular distribution

4. Ratio of coproduct B: Median-based triangular distribution

5. Percent allocation to parcel (or land entity): Median-based triangular distribution

6. Percent allocation to offshore: Median-based triangular distribution

The mathematical equations for the median-based triangular distribution are derived from 

probability theory in Crovelli (1999). The basic probability theory of the triangular 

distribution can be found in Law and Kelton (1991). The probability theory of the 

lognormal distribution is given in Aitchison and Brown (1957).

A probabilistic method must be derived that combines given random variables of the 

geologic assessment model to determine parameters (especially, the mean, standard 

deviation, F95, and F5) of new random variables of interest, which are functions of the given 

random variables. The new random variables of interest are the following measures of 

undiscovered petroleum resources:

 Oil in oil fields

 Gas in oil fields

 NGL in oil fields

 Gas in gas fields

 NGL in gas fields

 Oil in gas fields
A probabilistic method is required to compute the estimates in the form of parameters 

(especially, the mean for a point estimate, and fractiles F95 and F5 for an interval estimate) 

of a probability distribution. An analytic probabilistic method is a probabilistic method that 

uses mathematical equations from probability theory to obtain the estimates of the 

undiscovered petroleum resources in an assessment unit. The ASSESS method is an analytic 

probabilistic method that was developed by deriving the necessary mathematical equations 

based upon conditional probability theory and laws of expectation and variance. Two 

features of ASSESS are the following:

 ASSESS relates the parameters with mathematical equations.

 ASSESS computes the means, standard deviations, minimums, and maximums exactly.

 ASSESS computes the estimates instantaneously.

For example, in the case of oil in oil fields the following relationships are developed for the 

random variables:

N: Number of undiscovered oil fields 

X: Size of undiscovered oil field (mmbo) 

Y: Oil in undiscovered oil fields (mmbo)

N

1=1

The random variable Y is equal to the sum of a random number of random variables (sizes of 

undiscovered oil fields). The mean and standard deviation of Y can be derived from the 

theory of conditional probability and conditional expectation (Ross, 1993). Several 

parameters of oil in oil fields are the mean, standard deviation, minimum, and maximum:

°Y = Tj

Min(Y) = Min(N)Min(X) 

Max(Y) = Max(N)Mca(X)

Many of the mathematical equations for parameters of the new random variables of 

interest in the ASSESS method are derived using conditional probability theory in 

Crovelli (1992). A simplified flow chart of the analytic probabilistic method for resource 

assessment of conventional oil and gas accumulations - the ASSESS method - is 

displayed in figure 2.

SPREADSHEET SYSTEM

Given the geologic assessment model (the Seventh Approximation, figure 1), the analytic 

probabilistic method is used to create a spreadsheet probability system. The above analytic 

probabilistic method is incorporated into a spreadsheet software system called Analytic 

Spreadsheet Energy Software System (ASSESS). ASSESS consists of a series of 46 panels in 

the spreadsheet. A panel is a set of approximately 11 columns of related calculations. 

Because the total number of columns in ASSESS is approximately 500, it was necessary to 

construct ASSESS as a workbook with three worksheets called Cond, Uncl, and Unc2. Cond 

is comprised of Panels 1-22, Uncl has Panels 23-34, and Unc2 has Panels 35-46. Worksheets 

Uncl and Unc2 are linked to the worksheet Cond. The topics included in the worksheets 

Cond, Unc 1, and Unc2 are the following:

 Worksheet Cond: Input data (Panels 1-4), probability distribution calculations (Panels 

5-10), and conditional resource estimates (Panels 11-22).

 Worksheet Uncl: Unconditional-1 resource estimates using the geologic probability 

of the assessment unit.

 Worksheet Unc2: Unconditional-2 resource estimates using both the geologic and the 

access ("geoacc") probability of the assessment unit.

The individual panel numbers and contents of the spreadsheet ASSESS are given in 

Table 1.

A probability system is an orderly collection of random variables logically related in 

terms of their probability distributions and parameters. The spreadsheet probability 

system ASSESS includes:

Conditional (unrisked) and unconditional (risked) estimates of undiscovered petroleum 

resources in

 Assessment unit

 Parcel (or land entity)

 Offshore portion of parcel

The total number of new random variables or sets of estimates (mean, standard deviation, 

F95, and F5) per assessment unit:

 72 (2*4*3*3) if one parcel

 120 (2*4*3*5) if two parcels
For illustrative purposes, the ASSESS system is used to compute the undiscovered 

petroleum resource estimates in gas fields for four assessment units that were assessed by 

Christopher J. Schenk in an assessment of the Padre Island National Seashore (Schenk 

and others, 1999). The four assessment units are entitled: (1) Frio Rio Grande 

Embayment Gas, (2) Lower Miocene Rio Grande Embayment Gas, (3) Middle Miocene 

Rio Grande Embayment Gas, and (4) Vicksburg Rio Grande Embayment Gas. Note that 

the first assessment unit was used as an example of the basic input data form for the 

Seventh Approximation in Figure 1. The computer printout of the 46 panels in the 

ASSESS spreadsheet for this illustration is presented on following pages. The panel 

captions explain how the panels are related with respect to their calculations. For 

examples of particular interest, we have the following:

Panel 11. Conditional estimates of undiscovered resources in assessment unit: oil in oil 

fields and gas in gas fields. Mean, standard deviation, minimum, and maximum are 

computed by combining parameters from Panels 5 and 6. Fractiles F95, F75, F50, F25, 

and F5 are approximated by a lognormal distribution.

Note that the number of undiscovered oil fields (Panel 5) and the sizes of undiscovered 

oil fields (Panel 6) produce the oil in oil fields (Panel 11). Recall that the corresponding 

mathematical equations were given in the previous section.

Panel 23. Unconditional-1 estimates of undiscovered resources in assessment unit: oil in 

oil fields and gas in gas fields. Mean, standard deviation, minimum, and maximum are 

computed by applying the geologic probability from Panel 23 to parameters from Panel 

11. Fractiles F95, F75, F50, F25, and F5 are approximated by a lognormal distribution.

Note that the geologic probability (Panel 23) is applied to the conditional estimates 

(Panel 11) to generate the unconditional-1 estimates (Panel 23).

Panel 35. Unconditional-2 estimates of undiscovered resources in assessment unit: oil in 

oil fields and gas in gas fields. Mean, standard deviation, minimum, and maximum are 

computed by applying the geoacc probability from Panel 35 to parameters from Panel 11. 

Fractiles F95, F75, F50, F25, and F5 are approximated by a lognormal distribution.

Note that the geoacc probability (Panel 35) is applied to the conditional estimates (Panel 

11) to generate the unconditional-2 estimates (Panel 35).
